Definitions

  • the present invention relates to the field of traction apparatus in general, and in particular to a traction apparatus having angularly and laterally adjustable structural components to accommodate individual patients and/or medical procedures.
  • the angularly adjustable traction apparatus that forms the basis of the invention comprises in general, a main support unit, a limb immobilizing unit, a pulley unit, a track unit, and a pair of anchor units wherein the limb immobilizing and pulley units are angularly and laterally adjustable relative to the main support unit and the track unit and the pulley unit is vertically adjustable as well.
  • the main support unit comprises a base platform member that is dimensioned to fit under a patient's upper torso and the track unit comprises an elongated track groove formed in the platform member and dimensioned to slidably receive the limb immobilizing, pulley, and pair of anchor units.
  • the apparatus of this invention employs a plurality of quick release securing elements for angularly adjusting and maintaining the desired angular orientation of the various structural components.
  • the pair of anchor units are specifically designed to prevent the displacement of the limb immobilizing and pulley units once their desired positioning and angular orientations have been achieved.
  • FIG. 1 is a perspective view of the improved adjustable angle traction apparatus that forms the basis of this invention in use;
  • FIG. 2 is an isolated detail view of the limb immobilizing unit and one of the anchor units;
  • FIG. 3 is an isolated detail view of the pulley unit and the other of the anchor units
  • FIG. 4 is a top plan view demonstrating the relative position of the limb immobilizing unit, the pulley unit and both of the anchor units relative to both the main support unit and a patient's limb being placed into traction and,
  • FIG. 5 is an exploded perspective view of the pivoting arrangement of the limb immobilizing unit.
  • the angularly adjustable traction apparatus that forms the basis of the present invention is designated generally by the reference number 10 .
  • the apparatus 10 comprises in general, a main support unit 11 , a limb immobilizing unit 12 , a pulley unit 13 , a track unit 14 , and a pair of anchor units 15 . These units will now be described in seriatim fashion.
  • the main support unit 11 comprises in general an elongated flat rectangular base platform member 20 dimensioned to underlie a substantial portion of a patient's torso and rest upon the top of a medical examination table or the like.
  • the platform member 20 has top 21 , a bottom 22 , a pair of elongated sides 23 , 24 a front side 25 , and a rear side 26 .
  • the top 21 may be provided with a padded or cushioned surface 27 and the bottom 22 may be provided with one or more buckles 28 that are adapted to receive restraining straps 29 .
  • the track unit 14 comprises an elongated recessed track groove 30 extending along at least one of the elongated sides 23 , 24 of the platform member 20 .
  • the track groove 30 intersects at least one of the front 25 and rear 26 sides of the platform member 20 for reasons that will become apparent presently.
  • the limb immobilizing unit 12 comprises a generally C-shaped limb engaging member 40 having a padded interior 41 and being secured in a tangential fashion on a hollow tubular support arm 42 releasably received in a swiveling angularly adjustable collar element 43 suspended within a first support bracket 44 that is slidably received within the track groove 30 in the platform member 20 .
  • the support bracket 44 is further provided with one or more securing elements 50 that will captively engage the support bracket 44 at a desired location along the track groove 30 in the platform member 20 and the collar element 43 is also provided with a securing element 50 ′ that will releasably engage the hollow tubular support arm 42 so that the orientation of the limb engaging member 40 can be reversed 180° when desired.
  • the collar element 43 is pivotally mounted within the support bracket 44 as at 45 to vary the angular orientation of the support arm 42 relative to the support bracket 44 in the horizontal plane.
  • the collar element 43 is also provided with a securing element 50 ′′ to captively engage the collar element 43 at a desired angular orientation relative to the support bracket 44 .
  • one of the anchor units 15 is operatively associated with the limb immobilizing unit 12 and comprises an anchor bracket 60 slidably received in the track groove 30 in the platform member 20 .
  • the anchor bracket is operatively associated with an adjustable length tether element 61 such as a chain that is fixedly secured on one end to the support arm 42 of the limb engaging member 40 to prevent the support arm 42 from moving from its selected orientation when the traction forces are applied to a patient's limb.
  • the anchor bracket 60 is also provided with a securing element 50 ′′′ to maintain the anchor bracket 60 at a desired location within the track groove 30 .
  • the pulley unit 13 comprises an extensible pulley tower 70 mounted for pivotal movement in both the vertical and horizontal planes in a second support bracket 44 ′ that is slidably received within the track groove 30 in the platform member 20 and also provided with securing elements 50 to captively engage the second support bracket 44 ′ at a desired location within the track groove 30 as previously described.
  • the pulley tower 70 has a lower cylindrical portion 71 provided with a pair of flange ears 72 whose inboard ends are rotatably suspended relative to the cross arms of a cruciform shaped pivot element 80 whose stem is vertically pivotally suspended within the second support bracket 44 ′ as at 45 ′.
  • the pulley tower also includes a hollow upper cylindrical portion 73 that is telescopically received in the lower cylindrical portion 71 to vary the effective length of the pulley tower 70 in a well recognized fashion.
  • Both the upper 71 and lower 73 portions of the pulley tower are dimensioned to receive a traction applying member designated generally as 90 which includes a traction weight 91 connected on one end of a flexible traction cable 92 whose other end is releasably associated with a limb engaging element 93 such as the finger cot arrangement depicted in FIGS. 3 and 5.
  • the upper portion 73 of the pulley tower is also attached to one end of a tether element 61 ′ whose other end is associated with the other anchor bracket 60 ′ for reasons that previously have been discussed herein.
  • the upper portion 73 of the pulley tower is also attached to one end of a tether element 61 ′ whose other end is associated with the other anchor bracket 60 ′ for reasons that previously have been discussed herein.
  • FIG. 4 it can be seen that the apparatus 10 is employed to immobilize a patient's limb 101 while traction forces are applied thereto.
  • a patient is placed in a supine position upon the top of the platform member 20 and the limb engaging member 40 is angularly adjusted in both the horizontal and vertical planes to engage the patient's limb; whereupon, the first anchor bracket 60 is laterally adjusted in the track groove 30 to prevent the limb immobilizing unit 12 from becoming displaced.
  • the pulley tower 70 is vertically and horizontally angularly adjusted relative to the second support bracket 44 ′ after the second support bracket 44 ′ has been selectively positioned and secured within the track groove 30 and the other anchor bracket 60 ′ causes the tether element 61 ′ to resist the displacement of the upper portion 73 of the pulley tower.
  • the limb engaging element 93 is then attached to the free end of the patient's limb 101 and the weight 91 will place the limb 101 into traction in a well recognized manner.
